Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm A .&c>{B7  
Type: Double Bounces nSyLt6zn\  
The '****' denotes a possible internal focus n5kGHL2  
RMS is the RMS spot radius on axis at the primary wavelength. =F$?`q`  
RMS values of 0.00 indicate that an accurate RMS eZOR{|z  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 3eE=>E4,  
non-rotationally symmetric or uses non-standard surfaces.
